Integrated circuit package with glass layer and oscillator

Abstract

An integrated circuit package comprises an integrated circuit that comprises a temperature sensor that senses a temperature of the integrated circuit. A memory module stores oscillator calibrations and selects one of the oscillator calibrations as a function of the sensed temperature. An oscillator module generates a reference signal having a frequency that is based on the selected one of the oscillator calibrations. An epoxy layer adheres a glass layer to the integrated circuit. A packaging material encases at least part of the glass layer and the integrated circuit.
